RIGHT AND LEFT HAND STOP AND WASTE COCK.

SPECIFICATION forming part of Letters Patent No. 594,162, dated November23, 1897.

Application filed July 9,1897. Serial No. 643,997. (No model.)

To all whom it III/(Ly concern:

Be it known that 1, CHARLES F. SMITH, a citizen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements in Rightand Left Hand Stop and "Waste Cocks, of which the following is aspecification.

My invention relates to improvements in right and left hand stop andwaste cocks and the objects of my improvement are simplicity and economyin construction and efficiency in operation.

In the accompanying drawings, Figure 1 is a front elevation of my rightand left hand stop and waste cock. Fig. 2 is a plan View thereof. Fig. 3is a horizontal section on the line :0 as of Fig. 1, and Fig. 4: is adetached elevation of the plug.

A designates the body of the cock, which in its general features is ofan ordinary form and within the cross-bore of which the rotary plug B isfitted, the general form of said plug and the passages through it beingof the ordinary form. The main and waste passages through the plug areindicated by broken lines in Fig. 3. The body of said cock is providedat its handle end with a pair of fixed external stops 5 6 and also witha screw 7, the end of which extends into the bore of said body and formsan internal stop or pair of stops. The respective ends of the body aredesigned to be connected with the waterpipes in the ordinary manner, andthe middle portion of said body has the ordinary wastenozzle 8 on itsfront side.

The plug B is provided with an oblong angular neck or shank 9, Fig. 2,to receive the handle C, the opening in the head of which is of acorresponding form,whereby the position of the handle on the shank ischanged by half-revolutions. The handle is held in place by the nut 10.The plug is also provided with a reduced portion or groove 11, intowhich the end of the screw 7 enters, as shown in Fig. 3. This grooveextends around the plug for a little over half of its circumference, theends of said groove forming stopshoulders coacting with the screw 7, ashereinafter described. The handle is provided with a stop 12.

The cock is represented as arranged for a right-hand cock-that is tosay, the handle stands on the right-hand side and swings within theright-hand front quadrant of a circle around. the plug. When the handlestands lengthwise with the pipes connected with the body of the cock, asshown, the main passage 13,Fig.4, through the plug stands in alinementwith the pipes and the cock is open. In bringing the handle to thisposition the stop 12 engages the external stop 5 on the body and thuslimits it from moving rearwardly beyond the position shown. By pullingthe handle to the front the stop 12 is carried away from the externalstop 5, and the right-hand end (in the position shown in Fig. 3) of thegroove comes against one side of the interal body-stop or screw 7 at theend of a quarter-turn of the plug and stops the handle and plug with themain passage 13 closed and the waste-passage leading therefrom on theright-hand side of the cook, the stop 12 being about midwaybetween thestops 5 and 6, and the position now being determined by the internalbody-stop instead of an external stop, as before. By removing the handlefrom its shank and changing its position thereon one-half of arevolution the cock will be changed to a lefthanded cock. When thuschanged, the handie will swing in the left-hand front quadrant and bestopped in its parallel position with the pipes by the handle-stop 12and external body-stop 6 and in its position at right angles thereto bythe left-hand end of the groove in the plug and the internal bodystop.

By my improvements the construction is simple and inexpensive, while thecock isconveniently changed for either hand by merely 9o changing theposition of the handle on the plug. The internal body-stop and coactingpart of the plug are wholly inclosed and-protected where they arecompletely isolated from the external body and handle stops. By makingtheinternal body-stop in the form of a screw it can be withdrawn for theinsertion of the plug and then screwed in to properly project into thereduced portion of the p e- I claim as my invention-- 1. A stop andwaste cock having a body provided with a pair of external stops, a plugfitted to said body, a handle fitted to said plug and having ahandle-stop for engaging the said external body-stops, and an internalstop coacting with a portion of the said plug substantially asdescribed.

2. The combination of a cock-body having a pair of opposing externalstops, a handle having a stop for coacting therewith, a plug having areduced portion with stop-shoulders and an internal stop projecting fromthe inner wall of said body into the reduced portion of said plugsubstantially as described.

3. The combination in a stop and waste cock of a cock-body having a pairof stops, a handle having a stop for engagement therewith, a plug havinga reduced portion with stop-shoulders and a screw secured in said bodywith its end projecting into the reduced portion of said plugsubstantially as described.
